Hardware and structure-related
1. Q: What's the detection range and precision of the laser head?
A: The laser distance sensor can accurately detect distances under 6 m and has an error rate
of ±1% within 3 m, that is, a difference of less than 1 cm for a distance of 1 m.
2. Q: Is the laser sensor harmful to children or pets?
A: The laser distance sensor is designed in accordance with IEC 60825-1:2014 laser safety
Class 1 and will not generate hazardous radiation. It is tested in TÜV Rheinland laboratories in
Germany as described in the manual. Please rest assured during use.
3. Q: Is a dust detection feature provided?
A: No. As a home frequently using the machine will be very clean and tidy, the dust detection
feature is not practical. In addition, the dust detection feature may frequently fail and the sensor
may be easily covered or blocked by dust that may result in misjudgment, thus, this kind of
sensor has not designed to be used on the vacuum cleaner.
4. Q: What kind of fan is used and what is the suction capacity?
A: A world-class brushless fan manufactured by NIDEC is used. Maximum suction capacity is
2000 Pa, which is more than two times that of general robotic vacuum cleaners on the market.
5. Q: Is a dust bin detection feature provided? (Updated on July 04, 2018)
A: No. If the dust bin is not emptied for an accumulated usage period of five hours, the machine
will give a voice prompt to ask you to empty the dust bin and your mobile phone will also send
you a message to ask you to empty the dust bin. Dust bin sensors used in other commercially
available products are easily blocked by dust and thus frequently misreport that the dust bin is
full.
